Polycom PVX Release Note page 23

• Some laptops will slow the clock speed when running on batteries,
thereby causing the Polycom PVX software to show a processor alert. To
correct, connect the computer to AC power and restart Windows or
reconfigure the Power Options settings in the Windows control panel to
maximize performance (shorter battery time).
NAT/Firewall Traversal
• PVX does not save the Use UPnP router to detect address setting correctly
as part of a Profile. To work around this problem, manually re-enable this
setting when you switch to a Profile that should use UPnP.
• When the PVX system is configured to be behind a NAT/firewall and set
to use a UPnP router to detect the address, the IP address is not always
displayed on the home screen.
Network Issues
• The QoS tab on the Setup > Network page has been simplified so that a
single setting allows you to enable or disable QoS. In PVX version 8.0.0, IP
Precedence and DiffServ had to be set separately, which did not work
reliably on all Windows systems.
• Restoring the system to factory defaults does not reset the allocation of
system resources to the "Balanced" setting. The default port on a server is
typically 1002 or 389, depending on the installed versions of ILS and
Windows. Note that the default port for PVX is 389.
• If you change the Media port range on the Ports tab of the Setup >
Network page and then upgrade to PVX version 8.0.2, the values you
entered in the Media port range field will be set back to the default values.
• If you register to an invalid Global Directory Server, the PVX user interface
may hang briefly and then recover.
• Users with the Windows XP operating system will not be able to place or
receive video calls if the Internet Connection Firewall is enabled. To
correct this:
1. Right-click My Network Connections.
2. Select Network Properties.
3. In Local Area Connection Properties, select Advanced.
4. Clear the Internet Connection Firewall option.
• Users running Windows XP Service Pack 2 may experience difficulty
establishing a connection to incoming calls through a firewall. If this
occurs, do the following:
1. Click Start and then choose Settings > Control Panel.
2. Select Windows Firewall.
3. Select Exceptions.
